WALTER S. MINOR, OF CUNNINGHAM, TENNESSEE.

STAVE-J'OIN'IING MACHINE.

Application filed October 23, 1916.

b all whom it may concern:

Be it known that I, WALTER S. MINOR, a citizen of the United States, residing at Cunningham, in the county of Montgomery and State of Tennessee, have invented certain new and useful Improvements in Stave- J ointing Machines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved stave jointing machine and has for its primary object to provide a machine whereby the staves of barrels or hogsheads may be quickly and accurately out at the proper angle for jointing, irrespective of the width of the stave.

It is another object of the invention to provide a machine for the above purpose embodying a traveling carriage and means for automatically removing the jointed stave at the end of the operative movement of the carriage.

The invention has for another important object to provide operating means for the traveling carriage, and means automatically actuated by the carriage to render said op erating means operative and inoperative and to reverse the movement of the carriage after the discharge ofthe jointed stave.

It is also an important object of my invention to provide improved means for discharging the cut strips from the machine in the reverse or return movement of the carriage.

In its more specific aspect, the present invention embodies a divided carriage, one

. section of the carriage being mounted on a relatively stationary frame and the other upon a transversely tilting frame, a rotary saw mounted upon each of the frames, and means for adjusting the tiltable frameso as to space the rotary saws in accordance with the width of the stave, whereby the edges of the stave are cut on the proper angle.

It is also one of the detail items of improvement to provide a sectional traveling Specification of Letters Patent.

Patented June 12, 1917.

Serial No. 127,232.

With the above and other objects in View, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which,

Figure 1 is atop plan view of a stave jointing machine constructed in accordance with the preferred embodiment of the invention:

Fig. 7 is a plan view showing the automatic clutch shifting means in one position of the traveling carriage with the clutch in neutral position;

Fig. 8 is a similar view, the clutch being in operative engagement with one of the power transmission pulleys, and showing the carriage near the end of its operating movement;

Fig. 9 is a detail vertical sectional view showing the stave holding dogs at the forward end of the carriage; and

Fig. 10 is a similar view showing the holding dogs at the rear end of the carriage.

Referring in detail to the drawings, 5 designates the stationary frame section of the machine which is mounted upon a suitable base 6. A relatively narrow, vertically tilt ing frame section 7 is arranged at one side of the frame section 6, said frame sections being hingedly connected to each other at spaced points, as shown at 8. In the frame section 5, the transverse countershaft 9 is journaled in suitable bearings, and a similar countershaft 10 is also j ournaled in the tilting frame section 7 and connected to the countershaft 9 by a universal joint 11.

A saw mandrel 12 is mounted in suitable bearings 13 on the top of the main frame section 5 and a similar mandrel 14 is also mounted in bearings 15 on the top of the frame section 7. Circular saws 16 and 17 respectively, are fixed upon the opposed ends of the mandrels 12 and 14. These saws are v in radial alinement with the hinges 8 connecting the two sections of, the frame, this point representing the axial center of a hogshead-or barrel. The saw- 16 on the stationary frame section at all times remains in a vertical'plane coinciding with this center, while the other saw 17 isalways disposed at an angle to the perpendicular, but in any-of such angular positions on' a radialline coinciding with the hinge or pivotal center of the tiltable frame section.

The stave to be cut or jointed is conveyed to the saws by means of a carriage. This car.-

- riage likewise-consists of two sections 1 8 and 19 respectively, which are mounted for longitudinaltraveling movement upon the frame S6Ct1OIlS;5 and-7. ThGCiLlI'lflgB sections 18 and 19 are loosely coupled or connected.v to each other, as indicated at 20, so as to permit of the angular movement of the section; 19 with respect to the section 18. Each of-these carriage sections is provided with a pair of rollers 21 to travel upon a track rail 22 suitably secured to each of'the p a gear 26 fixed upon one end of a shaft 27 mounted in themain frame. section 5.

Upon the frame section 5, a longltu'dinal 7 rod 28is, mounted for sliding movement in the supporting brackets 29. This rod: is in two sections, andbetween the same a coil spring- 80 is interposed and suitably connected atits extremities to the rod sections. The extremities of the rod 28 are angularly and outwardly disposed, as at 31,for a purpose which will hereinafter appear.

A second longitudinally. disposed rod 32 is also mounted upon the frame section5 for rotative movement, and this rod isprovided with spaced,lradiallyv projecting pins desig-- nated 33, 3'4, 35, 36. and 37 respectively. Upon; the frame 5, adjacent tothe respective pins33, 34, 36and 37,011 the shaft 32,, horizon-tally disposed, angular. levers38, 39,- and 41 respectivelyarearranged., Theselervers have their angularly disposed ends 38,

39, 40, and 41 respectively, disposed con- '60 tiguoustothe. shaft 32, while theother arms of; the leversare pivotedupon the-frame. 5 and project outwardly beyondlthe side thereof, as clearly. shown in, Figs; 7and. 8. The an ar. em t e le s n 89 project toward each other and are disposed relation, to the, respectivesaw blades.

tends forwardly to the front of the machine and has a suitable operating lever42connected to said end ofthe rod, whereby it may be manually actuated. A transverse bar 43 is slidably mounted uponthe frame section 5 of, the machine and carriesa yoke 44, for engagement with the grooved collar 45 of a doublev clutch 46 vwhich is ;keyed for sliding movement upon the shaft 27 Specedbelt wheels 47 are loosely, mounted upon said shaft, with which the respective clutch heads engage.v The sliding bar 43 has an opening 48 therein to receive the pin: 35 on the, shaft 32. Atwistedpower transmission belt 49 connects one of the wheels 47 with ajbelt wheel50 fixedupon the counter-shaft 9, and av similar wheel 51 is connected by the straight belt 52 to the other, of .the wheels 47. A lug5=3is fixed upon the. section 18 of the traveling carriage to co-act with the outwardly projecting ends of the. pivoted levers 38,39,40. and 41, whereby the. clutch 46 is automatically shifted to operatively connect thewheels47' to or disconnect, the same, from the shaft 2 7, in the manner'which will be presently explained.

. Uponeach of. the frame sections 5 and-7, a strip receiving board ,54 and '55 respectively is. pivotally mounted as at. 56, for. vertical swingingniovement. Each of-thesc boards carries an angularly disposed cleat 57 on its upper surface normally (lisposed in spaced A fixed or stationary obliquely inclined deck 58 and 59 respectively is mounted upon each sectioneof the frame. Thestripboards 54 and are each actuated through the medium of vertically movable rods indicated at 60, said rods being connected at their upper ends to, the respective. strip receiving boards. A sectional shaft 61'ismounted in the frame sections5 and 7,said shaft; sectionsbei'ng connected'by. auniversal, jpint 62 which, of course,is 1n almement with the countershaft jolnt 1,1 and the hlIlg$b6tW811 the frame sections. Toeach section of-the shaft 61, a

downwardly projecting crank arm 63 is fixed, andto saidarms the lower ends of the respective. rods, 60 are ,operatively connected. An upwardly projecting: rod 64 is also. fixed in one sectionyofthe. shaft 61 and, to the same, one end ofa link 65: is pivotallyvcon nected.-, The. other end ofthislinkis slotted, asat 66 ,-to receive a pin 67 fixed in the lever 68 acentto its lower end. This lever, at its upper end, ispivoted. as at 69 upon a lug or bracket 70 fixed to the-framesection 7 To the section l9of the traveling carriage, a projecting pin or lug-71 is secured to engage the lower end of the lever 68 and actuate the several elements associated therewith in the return movement of the carriage after the stave has been cut, whereby the strip receiving boards 54: and 55 are elevated to the position seen in dotted lines in Fig. 2. The strips which have been cut from the edges of the stave are carried by the cleats 57 and directed over and upon the inclined decks 58 and 59 down which they move by gravity and are discharged upon the ground.

The stave to be jointed is securely held in position upon the carriage by means of the dogs 72 which are pivotally mounted as at 73 upon the forward ends of the carriage sections, the other ends of said dogs having lugs or shoulders 74 thereon which are held in engagement over the end of the stave resting upon the longitudinally curved upper edges of the carriage sections by means of the springs 75.

A dog 76 is also pivotally mounted as at 77 upon the rear end of each carriage sec tion and has an angular lug 78 on its upper end for engagement over the end of the stave while at its lower end each dog is formed with an angular-1y and downwardly projecting arm 79. A'coil spring 80 is con nected to each of these dogs 76 above its pivot to normally hold the same in yielding engagement upon the stave. The arms 79 of the latter dogs are adapted for sliding engagement upon a fixed trip plate 81 mounted upon each frame section, and as seen in Fig. 5, the dogs are thereby rocked upon their pivots and the upper ends 78 thereof disengaged from the stave. At the rear end of the machine above the plate 81, spaced transverse rollers 82 are journaled at their ends in suitable bearings or supports, and a forwardly and downwardly inclined guide 83 is fixed to the support and has its lower end angularly bent and upwardly defiected, as at 83. A rod 84 is suitably fixed upon each of the plates 81 and also has an upwardly and rearwardly projecting, angular portion disposed in parallel relation to the guide 83 and terminating at its upper end contiguous to the rollers 82. Rearwardly of these rollers 82, a third roller 85 is suitably mounted. The upper roller 82 is positively driven by a belt 86 which is engaged upon the wheel 87 fixed upon one end of the roller shaft, said belt passing around idler wheels 88 mounted upon the frame section 5 through a belt wheel 89 fixed on the countershaft 9. Thus, when the stave is released from the holding dogs 76, the rods 84: engaging against the under face of the stave as seen in Fig. 5, raise or elevate the same in the continued travel of the carriage and direct the stave between the rollers 82. The upper roller being positively driven, continues the movement of the stave rear wardly and over the roller 85, from which it is finally discharged.

' When the carriage is at the forward end of the machine in position to receive a stave, it will be understood that the carriage section 18 engaging the angular forward end of the rod 28 has forced the rod forwardly and expanded the spring 30, said spring acting to start the carriage upon its operative movement. In order to retain the carriage in this position, I have provided a suitable latch or holding mechanism which is illustrated more particularly in Fig. 3 of the drawings. This latch device consists of a rod 90 which is yieldingly held against movement by the spring 91 connected to one end of the rod, the other endof said rod having an angularly disposed lug 92 formed thereon. 93 designates a guard plate suitably fixed upon the frame section 5, extending over the rack bar 25 and having its forward end angularly and downwardly projected, as at 94:. A lever 95 is fulcrumed intermediate of its ends upon the under side of this guard plate, as at 96, and one end of this lever is connected by the link 97 to the forward end of the latch rod 90. A vertically disposed rod 98 is pivotally connected to the other end of this lever and normally extends above the upper edge of the carriage section 18. Upon the upper edge of the rack bar 25, a shoulder 99 is formed, with which the lug 92 on the latch rod 90 is adapted to co-act, whereby the rack bar and consequently the carriage upon which the rack bar is secured, is held against longitudinal movement under the action of the spring 30. It will be seen from this arrangement that, when the stave is placed in position upon the sectional carriage, it will engage the upper end of the rod 98 and force said rod downwardly, thus rocking the lever 95 and lifting the forward end of the latch rod 90 so that the spring 30 may contract and start the carriage upon its operative movement.

A rock shaft 100 is mounted in suitable bearings on the base 6 at the outer side of the tilting frame section 7. Spaced arms 101 are fixed upon this shaft and rods 102 pivotally connect the respective arms to the frame section 7 adjacent its upper end. An operating lever 103 is fixed to one end of the shaft 100 and is provided with the usual spring pressed locking dog for engagement with the teeth of a fixed rack or quadrant 104. It will thus be seen that, by the manipulation of the lever 103, the frame section 7 may be tilted to any desired angle and the rotary saw blade 17 disposed in proper position relative to the opposed saw blade 16, in accordance with the width of the stave to be cut.

. Upon the countershaft 9, a belt wheel 105 is fixed, with which the driving belt 106 extending from any suitable source of power, is engaged; A large belt wheel 107 & V

- tively, to the relatively small belt wheels 111 and 112 upon the respective saw mandrels 12 and'14, so that the saws 16 and 17 will be driven at, a very high speed.

A transverse shaft 113 is also mounted in suitable bearings on the frame section 5 between and in parallel relation to the countershaft 9. and the shaft 27, and upon one end of'this shaft 113 a suitable, fan 114 is secured. This fan shaftisdrivenfrom a belt wheelgl15 fixed upon the countershaft 9 connectedby a suitable driving belt 116 to a small belt wheel fixed upon the shaft 113. This fan is provided for the purpose of oreating a current of air in proximity to the dogs or levers 38 and 39 and preventing the collection of sawdust thereon which might possibly interfere with their proper operation.

Having now described the construction and arrangement of the several parts of the machine, its'operation will be understood as follows. After the frame section 7 has been properly adjusted to dispose the saw blade at the desired angle with respect to the relatively stationary blade 16, the stave; to be jointed is placed upon the upper edges of the two carriage sections 18 and 19, the forward end of the stave being forced downwardly under the dogs 76. The other end of the stave is then pressed downwardly until it is in contact with the upper curved edges of the carriage sections, when the dogs 72 will snap over the stave ends and thus hold'the same againstmovement on the car riage. As above stated in this application of the stave to the carriage, the latch element 90 is actuated to release the rack bar 25. The spring will thus contract which, together with a forward push on the carriage by the operator, will cause the lug 53 on the carriage section 18 to engage the first ofthe pivoted levers or dogs 38. The angular end of this lever engaging the pin 33, rocks the shaft 32 in the'proper direction to cause the pin 35 on said shaft to shift the sliding bar 43, thus shifting the double clutch 46 so as to operatively engage one of the clutclr heads with one of the belt wheels 47 to which the belt 49 is connected. The shaft 27 is thereby rotated and the gear 26 on this shaft co-acting with the teeth of the rack bar 25 continues the movement of the carriage, the two carriage sections moving together upon the respective frame sections 5 and 7. The saws 16 and 17 respectively operate upon the opposite edges of the stave to out or bevel the same upon the required angle. This rocking movement of the shaft 32 "also causes the pin 36 to act upon the pivoted lever 40 and dispose the same in a position at carriage is suiiiciently great to carry the lug 53 beyond the pivoted lever 41, said lever returning to its normal position in the path of movement of the lug. is released from the carriage and discharged from the machine in the manner above rethe angular end 31 of the rod 38 which acts as a bumper. The spring 30, by its contractile action, starts the carriage upon its return movement so that the lug-53 will engage the end of the lever 41 and rockthe shaft 32 in a direction to shift the bar 43 so that the clutch 46 is operatively engaged with the other of the belt wheels 47, thus reversing the rotation of the shaft 27 and consequently the movement of the carriage so that the return, movement of the latter will be automatically continued. The lever or dog 39 will have assumed a position at right angles to the line of movement of the carriage,and when the lug 53 engages this lever, the rocking movement'of the shaft 32 will again return the double clutch toits neutral position while themomentum ofthe carriage will be sufficient to return the same to its initial position where it is held by .the latch rod 90. The guard plate 93 obviates liability of the legs or clothing of. the operator coming in contact with therack bar 25. It will thus be seen that the machine is practically automatic in its action after the carriage has been started upon its movement and thelug 53 engaged with the first of the dogs or levers 38.

It will, of course, be understood that in the forward travel of the carriage, when the stave is being cut or jointed, the lug 71 on the carriage section 19 will engage the lower end of the lever 68 and move past the same. The pin 67 on the lever moves in the slot, 66 of the connecting bar so that no movement will be transmitted to the vertical rods 60. Upon the return movement of the carriage, however, the lug 71 engaging the lower end of the lever 68 (muses a pull upon the bar 65, thereby rocking the jointed shaft 61 and forcing the rods 60 upwardly so as to elevate the strip receiving boards 54 and 55 and discharge the strips therefrom upon the inclined decks 58 and 59, as heretofore explained. The strip boards immediately re- The stave l.-

ferred to, and the carriage finally engages turn to their normal horizontal positions by gravity after the lug 71 passe beyond the end of the lever 68 in the return movement of the carriage.

Ahorizontal beam 117 is fulcrumed intermediate of its ends upon a post or standard 118 arranged adjacent to the rear end of the tilting frame section 7 and is loosely connected at one of its ends to said frame section at the extreme outer side thereof. A

weight 119 is suitably secured upon the other tive to each other that they will not interfere by contact with a close arrangement of the carriage sections when a narrow stave is to be out.

From the foregoing description, taken in connection with the accompanying drawings, the construction, manner of operation and several advantages of my machine will be clearly and fully understood. It is manifest, of course, that the angle of the cutting action of the saws must be changed for every different width of stave, but in every case the bevel on the side edges of the staye will always be on a radial line intersecting the joint 11 between the countershaft sections and the hinge or pivotal connections between the two sections of the frame which represents the center of the hogshead or barrel. As the saws separate by the adjustment of the tilting frame section, the top portions thereof will, of course, separate faster than the lower portions, and as each stave, regardless of its width, must pass the saws at the same point above their axial centers and the medial portion of each stave at the same point relative to this axial center, it will be manifest that as the width of the stave is increased, the extent of its bulge or longitudinal curvature is proportionately increased. Thus, it is not a matter of importance that narrow and wide staves are used in the same barrel or hogshead. The bulge in the individual stave will be precisely proportionate to the total bulge in the hogs'head, in accordance with the width of the stave, and the diameter of the hogshead at the ends thereof will accordingly be the same. By means of my improved jointing machine, the staves may be quickly and accurately jointed, in precise accordance with the predetermined diameter of the hogshead or-barrel. The machine being almost entirely automatic in its action requires but little care or attention upon the part of the operator. As the several cooperating elements are of simple form and construct1on, it will also be appreciated that the machine is not liable to get out of order.

While I have shown and described the preferred construction and arrangement ofv the several parts, it is to be understood that the machine is susceptible of considerable modification therein and I, therefore, reserve the privilege of adopting all such lea stave in gitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.
